DOHC and SOHC clutch kits the same?

[FRpilot]

i thougth they were the same until my friend told me the pressure plates for the sohc is different than the dohc. they wont bolt up or something?

herse the situation. i have a dohc car with spec stage 3 and fidanza flywheel. i just bought an sohc auto car which i need to convert to manual. so i was hoping to take the spec stage 3 and fidanza and put it in my sohc car and buy a 100 oem exedy clutch kit to put in the dohc car so i can sell it. the sohc kit i see is for sohc and i thought it would fit my dohc but now im having 2nd thoughts..

does anyone know for sure b/c i hope i can use my spec stage 3 in my sohc. the flywheel should be universal but the clutch kit is what confuses me. i dont want to buy an sohc kit off ebay and find out it wont fit the dohc car. what should i do?
